Setting the bar for professional power stations. The B4000 doesn’t just deliver extremely high output, it does so with a class-leading power-to-weight ratio. Thanks to solid-state technology, it provides more power per pound than any other power station—and it’s safer, too. With 4,000 watts on tap, it’s perfect for home backup and even includes a 30-amp RV outlet for recreational use. And despite its capacity, it can charge from 0-80% in just over an hour.
The next generation of power is here with the B4000's advanced solid-state lithium battery, offering enhanced safety, stability, and performance for all your charging needs.
Introducing our sleek solid-state portable power station, designed for easy portability. With its ergonomic, lightweight build and aluminum soft-grip handles, it's perfect for reliable power wherever your adventure takes you.
Advanced GaN (Gallium Nitride) based transistors operate with greater efficiency than their traditional silicon counterparts.
Reduced Energy Loss
Increased efficiency results in less energy loss - meaning your Yoshi- no portable power station provides even greater competitive units not using GaN.
Improved Lifespan
Increased efficiency also means lower internal temperatures by up to 30°C (86°F) - directly resulting in a longer working life for critical components.
The B4000 is built to last, with a 5 year warranty and ETL certification that ensure its quality, reliability, and compliance with industry standards.
Transform the solid-state portable power station into an eco-friendly solar generator with optional Yoshino solar panels. Effortlessly recharge and enjoy limitless power, all while embracing sustainable energy solutions.

The B4000 is designed to power up all your devices with ease and efficiency. With multiple ports, including two USB-C ports and two wireless charging pads, you can charge a wide range of devices simultaneously.
Check your power station's status, charge levels, runtime, and settings right on your phone. The Yoshino App puts you in complete control of your portable power.
A: The B4000 uses a solid-state Li-NCM 54A battery, which provides reliable and long-lasting power.
A: The B4000's AC output ports can power most household appliances. However, before connecting an appliance, please make sure that the power of the appliance is within the rated power (4000W rated / 6000W max) of the power station to ensure safe operation.
A: You can check the charging time shown on the B4000’s LCD Screen. This can help you estimate the charging time of most appliances. For a more detailed calculation, see below:
You can calculate how long your device will last when powered by the B4000, by taking into account the limits imposed by the B4000's depth of discharge (95%) and inverter efficiency rate (90%).
(Power Station Capacity × Depth of Discharge × Inverter Efficiency) ÷ Device Rated Power
So for example, a 60W CPAP machine hooked up to the B4000:
(2611 Wh × 0.95 × 0.9) ÷ 60W = 37.21
So, in this case, the B4000 can power the CPAP machine for almost 37.21 hours.
A: Yes, the B4000 SST can charge and discharge at the same time.
A: Yes, the B4000 SST has fan(s) that will automatically turn on to keep the unit from overheating.
A: When the product is charging, the charging indicator icon will flash, and the remaining time will be shown on the LCD screen.
A: Use a soft dry towel to wipe gently across all surfaces.
A: If your portable power station is not going to be used for extended periods of time, power off the unit and disconnect the AC adapter from the outlet. Store it in a safe dry place with a temperature of 32-104°F / 0-40°C and humidity within 90%. Every 3-6 months charge the product to at least 80% to protect its battery life.
